Frequently Asked Questions
Is a 10,000mAh power bank allowed on planes?
Yes. Most airlines and aviation authorities permit lithium power banks up to around 100Wh (about 27,000mAh at 3.7V) in carry-on baggage; 10,000mAh is well within typical limits. Always carry the bank in your carry-on, not checked luggage, and check your airline’s rules before flying.
Do magnetic (MagSafe-style) power banks work with phone cases?
Many magnetic power banks are designed to work through thin cases (often up to 2–3mm). Product specs usually indicate case compatibility; thicker or metal cases may interfere with the magnetic connection and charging efficiency.
How many full charges will a 10,000mAh power bank give my phone?
Real-world results vary by phone model and efficiency, but expect roughly 1–2 full smartphone charges from a 10,000mAh pack. Some energy is lost during voltage conversion and through cables, so manufacturers’ mAh-to-charges estimates are approximate.
